DEFINITION

Classification: 152/89

The coil spring support for the spring encircling rigid annulus in the spring wheel consists of a plurality of coil springs, some of which are arranged within the wheel differently from others. The difference must be such that

each spring arrangement would fall in a different subclass hereunder.

(1) Note. For coil drive springs arranged differently from supporting springs, see this class, subclasses 101, 104 and 107.
